My impression of Buttigieg took a big hit with last week's debate and this debate. Even though for the most part he answers well and has good moments, as a matter of fact he comes across as fake, as in rehearsed posturing to be seen as the level-headed good guy. I think I just don't like him in a visceral way. I never liked Warren, she recovered my esteem last week, just to lose it again this week. I find her pretty annoying.
I'm a bit troubled with the fact that Bernie didn't handle well the pressure and the attacks. This doesn't bode well for the continuation because he'll be attacked more and more, and then, if he wins the nomination, he will be brutally attacked by Trump and the right wing.
Bloomberg came across to me as competent, a big contrast with him coming across as an asshole last time.
Steyer had some great moments but he is irrelevant to the race.
Amy also did well but again, she has always polled in the single digits, she has no chance.
Bernie efficiently pandered to his crowd, trying to solidify his AA support.
I think this race may very well become one between Bloomberg, Sanders, and Biden.
I can't see how Buttigieg, Klobuchar, Warren, and Steyer would be able to win the nomination.
If Biden recovers hugely, wins SC, and does well on ST he will be back and the race will remain a 3-way one. If he loses SC he is toast since the lack of any momentum will hurt him on ST too, and the race will be only between Bloomberg and Sanders.
As of now I think Sanders is still the most likely one to win the nomination, followed by Bloomberg, then Biden, and all others have zero chance.
